I'm in the middle of dremelling out the Red 22 shifters to fit the Schmolke clamps. Couple of observations: for the Red 22 shifter bodies I'm having to remove shit loads of material to make them fit - bit nerve wracking! Also gotta say I'm umimpressed with the carbon clamps, they're as ghetto as my old BTP clamps. Not what I expect from Schmolke. Still hope for about 9g once I get some alu nuts through. For the carbon bolts the plan is to use M4s for RD limits and b-tension. There's very little to be saved over alu in such small sizes but it's bling! I'm going to try and drill out M6 carbon bolts for adjusters on my brakes and RD, but only when I re-cable the bike because nobody's got time for that! If it works, it should be about the same weight as plastic but less bendy and should stand up to the elements better. I got a couple of M5s - I might be able to use for FD hanger and cable clamp...
The Sram clamp and slot in the shifter body are tear drop shaped, so it tapers in at the top where the bolt goes through. Shimano/Campy are just round. Also the slot for the Sram clamp is 50% too narrow.
How do carbon bolts even work? Are they super-accurately moulded? 3D printed? Would seem like maybe one of those situations where alloy might actually be lighter than carbon Please enlighten me! (lol enlighten )

I found M5 for bottle cage bolt to be slightly large (I didn't measure the thread) but was already pretty tight at the point the top of the (countersunk) bolt was snug. Also the allen key slot for those is more like 1/8" rather than M3 - think that's down to poor tolerance.
Other than those rogue countersunk M5s, no issues so far. I did get carried away with an M5 brake pad bolt, and snapped the head off when tightening (that helped me get a feel for it)!
They do seem to stay snug with pretty low torque hand tightening (allen key). I just tend to go til it's tightish then another 1/4 turn. Grease is good at low torques as you know. Carbon is lighter, but in the smallest size (M4) the difference is minimal over a light alu bolt. I think the heads tend to be larger than metal, probably because of the difficulties involved in manufacturing such a product.
That's good to hear, normally you just see some bling pics of the end product and you don't hear about the hours of breathing in plastic and wondering whether it's an endeavour too far!
Like I said, the heads are kinda big, but not too ugly I don't think. I use THM padholders and just under the bolts some little nylon washers - not needed really but they make me feel a bit more secure! The bolts are about 0.5g from memory. They get the brakes down to 98g before pads.
Bit of a story about the Darimo post... I challenged them to get under 60g, but they said it came in at 62g (they sent a photo of it), and they were willing to make another for me. That was 14 days ago so hopefully in the coming weeks I'll have a seatpost on this bike (cos I sold my AX already)! Just can't wait for it to arrive as the weather is slowly improving here.
Not installed them just yet, as I've been waiting for nuts to arrive from Toronto Cycles that were delivered today. Unfortunately they only sent the nuts (less than 1/4 of my order), but it was the bits I really needed.
I've emailed them so we'll have to see what happens... Here's them ready to install. I'll use carbon paste on the insides of the clamps and on the bar for sure.
Looking at the price of a Darimo seatpost I shudder to think how much that will cost! Is that 60gm including all the hardware or just the post sans hardware? I'm guessing it was a special order since the 25,4m isn't on their wesbsite, is it?4ibanez wrote: ↑Tue Mar 06, 2018 8:56 pmBit of a story about the Darimo post...
